Step-by-step explanation:
Hi,
f(x) = (x - 1) - 3
The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)
And the -3 is not embedded with the x, meaning the function will move 3 units down.

Rita feeds her dog 3/4 pounds of dog food for each meal. Rita has just bought 24 pounds of dog food. For how many meals will the food last?
Answers
Answer:
32 meals
Step-by-step explanation:
Pounds of food per meal = 3/4 pounds
Pounds of food purchased = 24 pounds
Number of meals which the food can last up to, n = pounds of food purchased ÷ pounds of food per meal
n = 24 pounds ÷ 3/4 pounds
n = 24 * 4 /3
n = (24 * 4). / 3
n = 96 /3
n = 32 meals
The test to determine the presence of a certain virus in a pigeon is 97% accurate for a pigeon that has the virus and 99% accurate for a pigeon that does not have the virus. In a given population, 1.5% of the pigeons are infected.
Do not round your answer.
The probability that a randomly selected pigeon gets an incorrect result is
Answers
Before finding the probabilities, we need to find all possible outcomes, and it's probabilities.
Doing this, we get:
The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.
Possible outcomes:
Pigeon has the virus(1.5% probability) and gets an accurate test, showing the presence of the virus(97% probability).
Pigeon has the virus(1.5% probability) and gets an inaccurate test, not showing the presence of the virus(100% - 97% = 3% probability).
Pigeon does not have the virus(100 - 1.5 = 98.5% probability) and gets an accurate test, not showing the presence of the virus(99% probability).
Pigeon does not have the virus(98.5% probability) and gets an innacurate test, showing the virus(100 - 99 = 1% probability).
Probability of incorrect result:
Has the virus and test negative: 0.03 of 0.015
Does not have the virus and test positive: 0.01 of 0.985
Thus:
[tex]p = 0.03\times0.015 + 0.01\times0.985 = 0.0103[/tex]
The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.

Armed gunmen shoot a victim who is 5.9 ft tall, from the roof of a building that is 146 ft away. If the roof of the building was 385 ft high, at what angle to the horizon would the bullet have been fired?
Answers
The bullet has been fired at an angle of 69.5° to the horizon. This is a problem based on the application of trigonometry.
Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles.
Given that
Distance between the building and the man = 146 ft.
Height of the man = 5.9 ft.
Height of the building = 385 ft.
So,
Total height = Height of the man + Height of the building
= 5.9 ft. + 385 ft.
= 390.9 ft.
Let the angle to the horizon would the bullet have been fired be x°.
[tex]tanx^o = \frac{390.9}{146}\\tanx^o = 2.677\\x = tan^{-1}(2.677)\\x = 69.5[/tex]
Thus, the bullet has been at an angle of 69.5°.

Answer:
y = 2.5 ft4y = 10 ftStep-by-step explanation:
The perimeter is the sum of the side length. Each of the sides shown has the same length as its opposite, so the perimeter is ...
P = 2(4y +y) = 10y
Using the given value for perimeter, we find y to be ...
25 ft = 10y
2.5 ft = y
__
Then the longer side is ...
4y = 4(2.5 ft) = 10 ft . . . . length of longer side
Find the measure of C for the circle :

Answer:
x = 72
Step-by-step explanation:
∠DBC is an included angle and arc DB is its corresponding arc
Relationship between an included angle and its corresponding arc: an included angle is equal to one half of its corresponding arc
so
∠DBC = [tex]\frac{1}{2}[/tex] arc DB
we are given that arc DB = 144
so we exchange arc db with 144
∠DBC = [tex]\frac{1}{2} 144[/tex]
[tex]\frac{1}{2} 144=72[/tex]
so we can conclude that ∠DBC (x) = 72

You are standing on a footbridge that is 12 feet above a lake. You look down and see a duck in the water. The duck is 7 feet away from the footbridge. What is the angle of elevation from the duck to you? Round your answer to the nearest tenth.
Answers
Answer:
59.7°
Step-by-step explanation:
Working based on the solution diagram :
The angle of elevation = x
From trigonometry :
Opposite side = 12 feets
Adjacent side = 7 feets
Tan x = opposite / Adjacent
Tan x = 12 / 7
Tan x = 1.7142857
x = tan^-1(1.7142857)
x = 59.744°
The angle of elevation from the duck is 59.7°
